Project Details

Sources and trophic transfer pathways of thiaminase in food webs have not been characterized. The project identified species (including plankton, benthos, and fish) and trophic pathways associated with thiaminase in Great Lakes food webs. Identification of thiaminase sources and their trophic pathways is required for the development of management strategies to mitigate Thiamine Deficiency Complex. They surveyed all trophic levels at one site three times to identify sources of thiaminase and pathways of thiaminase transfer.
